  • Patent number: 11325178
    Abstract: A pressing tool for pressing fittings to produce pipe connections, with two opposing pressing jaws, each having a pressing section and a lever section, and having a retaining element for swivel connecting the pressing jaws, wherein the pressing sections form a receiving section and wherein pressing the lever sections apart causes the receiving section to close. An actuator spindle, a spindle nut and at least two actuator levers are provided, and each actuator lever is swivel connected at one end to the lever section of a pressing jaw and each actuator lever is swivel connected at another end to the spindle nut. A method for pressing fittings for the production of pipe connections is also disclosed.

  • Publication number: 20200230686
    Abstract: The invention relates to a pressing tool for pressing fittings to produce pipe connections, with two opposing pressing jaws, each having a pressing section and a lever section, and having a retaining element for swivel connecting the pressing jaws, wherein the pressing sections form a receiving section and wherein pressing the lever sections apart causes the receiving section to close. The technical problem of pressing fittings to produce pipe connections in a simple and cost-effective manner is solved by the fact that an actuator spindle, a spindle nut and at least two actuator levers are provided, that each actuator lever is swivel connected at one end to the lever section of a pressing jaw and that each actuator lever is swivel connected at another end to the spindle nut. The invention also relates to a method for pressing fittings for the production of pipe connections.
